TILE-PRESS.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed. May 9, 1911. Serial No. 625,987.

To all whom it may concern Be it known that I, SEooNDo GILETTI, citizenof the United States, residing at Oakland, in the county of Alameda andState of California, have invented new and useful Improvements inTile-Presses, of which the following is a specification.

This invention relates to machines for making tiles, bricks, mosaics,etc.

The special object of the present invention is to provide a practical,simple, continuously-operating machine for the manufacture of tiles,such as are used in floors, pavements, etc., and particularly to providea machine in which a number of tiles of various shapes and sizes can bemanufactured simultaneously without interrupting the operation of themachine; and to provide means whereby the tile-forming members may beeasily removed and others substituted capable of producing otherdesigns.

The invention consists of the parts and the combination and constructionof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is a sideelevation of the machine. Fig. 2 is a vertical longitudinal section ofthe same. Fig. 3 is a front elevation. Fig. 4 is an enlarged sectionaldetail, showing the plungers and matrix. Fig. 5 is an enlarged detail ofa portion of the matrix belt. Fig. 6 illustrates forms of matrix slatsin cross section. Fig. 7 illustrates styles of tiles.

A represents an imperforate platen drum, having a polygonal surface,with sprocket grooves 2.

33 are endless chains carrying cross mold-slats4 and passing around theplaten drum A and an end idle drum 5. The chains are composed of linkspivotally conpairs by the cross pivot rods 6, which fit the grooves 2 inthe drums A-5. The several slats 4 are removably and interchangeablyconnected at their ends to the parallel chains 3 by means of screws 8,Fig.

" 5, to adapt. the machine to different sizes and shapes of tiles, aswill be shortly explained. Each of the several slats, which may be ofany suitable materlal, is provided with a number of perforationsextending entirely through the slats, which perforations are differentin the several slats and form matrices in which may be compressedsuitable cementitious material, and which take the form in outlinesimilar to the contour of the matrix in each slat. Fig. 7 showsdifferent forms of tiles.

Coacting with the mold or matrix belt formed by the connected slats andchains is a plunger or die-carrying cylinder 9, the periphery of whichis provided with a number of longitudinally extending undercut ordovetailed recesses 10 in which are insertible the removable andinterchangeable plunger bars 11, secured upon the exposed surface ofwhich areanumber of plungers or male dies 12; those on any single slatbeing alike, but the dies on successive slats may be different accordingto the number of different kinds, sizes and shapes of tile it is desiredto make at one and the same time.

In arranging the matrix slats 4 with their various molds upon the belt,they are so adjusted successively as to register or coincide withcomplementary plungers 12 carried by their respective die bars 11 whichare inserted upon the cylinder 9. The upper or exposed surfaces of theslats 4 and the plunger-carrying bars 11 are preferably curved in anarc, the radius of which is equal to the radius of the pitch linebetween the drum A and cylinder 9 so as to form the tiles with parallelupper and lower surfaces.

The material of which the tiles are composed is fed between thecylinders A and 9 through a suitable hopper or feed box 13 which is openon one side, as at 14:, so that an operator may have access and be ableto properly distribute the material longitudinally across the matrixslats 4 as they are exposed in the lower portion of the hopper 13 andinsure a proper feed of the material into the matrices of the slats 4:.The revolving drum A carries the slats 4L upwardly beneath the coactingcylinder 9, and the plungers 12 coincide with and project into thematrices a sufficient depth to compress the material in the matriceswhich is supported during compressions upon the platen surfaces of thedrum A. As the macontinues movlng,

terial is compressed in the slats the belt carrying the compressed tilesin the matrix openings until they register with ejecting plungers 15,secured upon the upper surface of removable and interchangeable bars 16carried by a cylinder 17, whihc is supported upon a suitable shaft 18journaled in the frame of the machine. As each of the matrix slats 4:passes below the drum 17 the compressed tiles are ejected from theirrespective slats by drum 17 and deposited upon an underneath conveyer20, by which latter they may be delivered upon a transversely disposedconveyer 21 and carried thence to one side of the machine and dischargedat a convenient place.

One of the salient features of the present invention is the provision ofthe belt in which are mounted the slats 4:, each of which is providedwith a number of matrix or mold perforations, and there can be made inthe machine at one time as many varieties of tiles as there arepolygonal surfaces upon the platen drum A. If drum A has twenty-four ofthese platen surfaces there can be manufactured at one operation of themachine twenty-four varieties of tiles and as many of each variety asthere are perforations in each matrix slat 4. By making the slats 4: ofdifferent thicknesses, or, in other words, making the matrix openings ofthe slats deeper insome slats than in others, tiles of differentthicknesses may be manufactured; but in performing this operation it isnecessary that the platen surfaces be at corresponding distancesradially from the center of the drum 2 for the reason that the pitchdiameter or pitch circle in which the sprocket chain forming belts 6move must be uniform, while the platen surfaces, upon which each slatrests as it moves around with the drum, may be 'varied in distance fromthe center. For that reason the depth of the slats is shown varied inthe diflerent tile making matrices shown in Fig. 6.

Another important feature of the invention is that by a machine of thissort with revolving plungers and horizontally moving matrices I am ableto produce tiles whose upper and lower surfaces are in flat parallelplanes. This is accomplished, (see Fig. 4:) by forming the exterioroperative face 12 of each plunger or die 12 with a curvature of suchradius as will produce a surface upon the material in the mold slat oneflat plane parallelwith the bottom of the tile which rests against theplaten surface.

It is obvious that when a very thin tile is to be manufactured therequisite matrix slat 4 will be made sufliciently deep to receive thenecessary volume of tile forming material and the slat will rest uponone of the platen surfaces most distant radially from the center of thedrum A. The variation in the distance of the platen surface from thecenter of the platen drum may be accomplished by attaching to the platendrum surfaces shims a of different thicknesses, Fig. 8.

In order .to break lumps of plastic material as they enter the hopper13, a rotary brush 24 is mounted above the opening 1& and forces thematerial against the adjacent wall so that all lumps are destroyed. Asthe material accumulates on the mold slats passing under the hopper, ascraper 25, arranged adjacent the plungers 12, scrapes off the excessmaterial and keeps the slats clean.

Having thus described my invention, what I claim and desire to secure byLetters-Patent, is i 1. A continuously operating tile press consistingof an endless, slatted belt, the slats of said belt having matrixforming perforations, polygonal drums around which the belt passes, thepolygonal faces of the drums supporting successive slats, a rotaryplunger cylinder having projecting radial plungers corresponding to andfitting the respective perforations, but not extending clear throughtheperforations, said plunger cylinder disposed contiguous to andperpendicularly above one of said polygonal drums so that each plungeras it enters a perforation will compress the material. to be acted onagainst a surface of said polygonal drum and said drum will directlyresist the pressure of said cylinder, a hopper arranged at the end ofthe machine outside the belt and in the angle between theplungencylinder and complementary drum, the slats of the belt forming aninclined feed floor for the hopper, and a scraper contiguous to the beltadjacent to the engagement of said plungers with the perforations.
